The ZWO ASI533MM Pro Imaging Kits include the following items:
The ZWO ASI 533MM PRO is the long-awaited monochrome version of the incredibly popular ASI533MC Pro cooled camera and features a 9Mp back-illuminated CMOS sensor with 91% quantum efficiency at 460nm.
The ZWO Mini Electronic Filter Wheel weighs only 300 grams, it is CNC machined and the optical thickness is only 20mm. This model can take 5 x 1.25″ mounted or 31mm unmounted filters.
The power absorption of the EFW is only 120mAh @ 5V so any USB cable can power it up. The distance between the filter and sensor of the Pro cameras like the ASI533 is circa 10mm. This close distance prevents any vignetting with 1.25″ filters for telescopes up to f/5. For f/2 lenses/telescopes it is necessary to use 31mm filters.
ZWO LRGB filters are designed to have a balanced spectral response with modern CMOS monochrome cameras. Each filter is optically polished and multi-coated.
Optolong LRGB & 7nm SHO filters provide excellent transmission over 80% and off-band blocking, making them a great choice for an affordable price.
Antlia LRGB & 3nm SHO filters give professional, high contrast results even under very light-polluted skies. The maximum transmission is between 88-90% with transmission off-band only 0.1%.
